Standard Threaded Well for Industrial Glass Thermometers
Series 445L
Application:
Fits
liquid-in-glass thermometers made to S.A.M.A. standards. Tapered
bore is made .008 in. oversize to eliminate possibility of
thermometer bulb expanding into the well, thus preventing
removal.
Connection Size: 3/4" NPT and 1" NPT are standard.
Other thread sizes are available upon request.
Materials:
Brass (ASTM B-16), Carbon Steel (C-1018), A.I.S.I. 304 & A.I.S.I.
316, Monel. Many other materials available on request.

Where single
values appear in the velocity tables, these may be considered
safe for water, steam, air or gas. In the shorter insertion
lengths, consideration is given to the velocity pressure effect
of water flowing at higher velocities. The values in parentheses,
therefore, represent safe values for water flow, while the
unbracketed values may be used for steam, air, gas and similar
density fluids.
